// C and C++ have two forms of unspecified behavior: undefined behavior and
// implementation-defined behavior.
//
// Programs that exhibit undefined behavior are invalid. Compilers are
// permitted to, and often do, arbitrarily miscompile them. BoringSSL thus aims
// to avoid undefined behavior.
//
// Implementation-defined behavior is left up to the compiler to define (or
// leave undefined). These are often platform-specific details, such as how big
// |int| is or how |uintN_t| is implemented. Programs that depend on
// implementation-defined behavior are not necessarily invalid, merely less
// portable. A compiler that provides some implementation-defined behavior is
// not permitted to miscompile code that depends on it.
//
// C allows a much wider range of platform behaviors than would be practical
// for us to support, so we make some assumptions on implementation-defined
// behavior. Platforms that violate those assumptions are not supported. This
// file aims to document and test these assumptions, so that platforms outside
// our scope are flagged.
